r "lhis i nvention relates to apparatusforstencil ing articles, such ascharacter dolls, toysQorthe likepand fin particular relates to apparatus for stenciling such articles with paint spray. Q

3 Heretofore, itflhas been the practice to paint articleslof the character described by first placing the granting sectional stenciling mask and then spraying paint through openings therein1 to stencilpredetermined areas of the article. now everQtjo preventthe paint from firmlyadherihgto the outer surface of themask, it has been custo maryto coat the same with a suitable lubricant, so that an operator, in handling the registering sections of the mask-and removing or replacing thecarticle therein, frequently markeclor soiled the article grease, paint, or other substances adhering to his hands. Such soiled farticles were either discarded dream as seconds.

npurpose of this invention is to provide ape paratus of the character described; in which an article may be positioned in or removed from the paintingfrnask. witltioutmarking or soiling the v Ofthe,,accompanyi large d circularfcolljarj I which journals in bore simrileaQjefficier-rt apparatusof the characterl described, in which articles may; be sprayepainted withfmaximurn speed, and, with a minimum amount ofhandlingof thearticle-retaining mask by theoperator.

u A substantial portion of shaft at the Lope posite end from handle It may be longitudinally split or cut out at W toprovide an armfllt the latter preferably having formedjthereon a bi;

furcated head 26 for receivingrshaft l3 at a point intermediate the uprights M and ii, and a pivot pin 2 l beingextended through head and shaft l3 to permit arm l3 to be swung to and'frorn registry with the cutout portion 53 of the shaft. Collar l5 maybe radially slotted at Zl snugly to "receive an integral cooperatingflange 22 on arm 53 to lock said arm against relative rotatijonal movement on theshaft, theouter surface of flange 22 being arcuate to correspond to the 'b ear ing surface of collar l5 (s ee'Figure 4));A slot flange 22 or arm 13*, may extend outwardly from bore It, so that when shaftlilcarrying arm 13 is rotated to one position ther'eof with flange 22 inline with the slot, as shown in Figure 4, springs 24, 2 extended between the arm and outwardly extending brackets 25, ZifiXQd on head 2%, will 15 23, in upright ll, ofslightly greater width than yieldably urge arm 13a outwardlyithrough slot 2M0 the chain-dotted position v ofthe arm, shown in Figure3. A curved plate 26, secured to p upf right i l l and having an l upwardly extending slot 2'! for receiving shaft l3 and arm Is may be provided to limit the upward swing of arm He by engagement with the upper end of the slot 213. In the open positions of arms I3 engagement of the latter with the sides of slot prevents rota tioh of shaft it in its ltlearings in uprights l4 and ll of bracket l2.

For clamping arm HR in registry with shaft f3 so that the shaft andthe arm maybe rotatedas a unit in bracket l2, there may beprovidedoutwardly adjacentsupport la reciprocableiu shaped member or yoke 228, the curved upperend ofwhich is of suchjradius as tdengagdabout shaft l3 and arm lit? to permit rotation of the l same. Extending downwardly from yoke 28 may be a rod 29, the lower end of which connects a suitable foot-treadle 3|] pivoted to a block 3jlon the floor. This arrangementis such thatfdo wnward pressure applied to treadle 3i) will yieldingly urge arm it through the aligned slots 23 and U and into engagement with' shaftl3.

On the outwardly extending ends of therod I3 and arm ll"; may befixed a pair of blocks 32, 32

-; havingslots 33, 33 therein for removably and replaceablyreoeiving projecting bars 3 3 and 35 of a pair of registering sections 36 and ill, respectively, of a stenciling mask 38, sections 3i!- and 3| being secured in blocks 32 by means of thumb screws The mask 38 is of known type having suitable shaped cavities therein for snugly receiving an article, such as a rubber character doll 39 or the like, and is provided with suitable openings 40, of predetermined shape and size to permit penetration of spray to predetermined areas of the doll, as will subsequently scribed. v I

The mask 38is rotated, as required, to expose be dethe various openings therein and a fine spray of paint-is applied through these openings by means of a suitable pressure spray-gun 4|, pressurefluid being supplied to the gun, through, piping 42, from a constant source of supply not shown. When gun 4| is not in use,"it may be hung on a hook 43 on support I.

Rearwardly and closely adjacent mask 381 is a hood 44, to which is connected a pipe from a suitable suctionmeans for carrying off excess section 36, places it on a moving conveyor 416 at the rear of the painting apparatus, and insertsanother doll to be painted; Next, by applying pressure on treadle 30 with his foot, arm l3 is swung inwardlyon pivot 2| tobring the mask sections 36, 31 into registry, arm l3 being yieldingly held in clamped position against the shaft I3 by the curved end of yoke 28. While the mask sections are thusheld in registry, the operator may turn crank |8with one hand, to rotate shaft I3 and arm l3 as av unit. The spray gun 4| is held in the. other hand, substantially in the posi tion shown in chain-dotted lines in Figure 2, and

1 paint issprayed through the various openings 40 a to without departing from the spirit thereof in'the mask, thereby applying coatings of paint to the portions of the doll 39 exposed through said openings.

With the apparatus shown and described the operator can use one hand to operate the spray gun 4|, while the other hand is kept clean for removing or replacing 'dolls in the mask 38, it

being .unnecessary forthe operator at any time to handle the lubricant and paint covered sections 36 and 31 of the mask, to open or close the same.

g It is, understood that a number of units of the apparatus shown and describedmay be placed at a plurality of stations for performing various coloring operations on the same doll. However,

several different colors may be applied at one station when the openings 40 of mask 38 are far enough apart that spray applied to one opening will not reach another where a different color is required.

Modifications of the invention may be resorted or the scope of the appended claims.
